Configure and register iSCSI connections
4. In the
iSCSI Targets and Connections
window, select one of the following, as
appropriate, to discover available iSCSI target ports.
•
Discover iSCSI targets on this subnet
- Scans the current subnet for all
connected iSCSI storage-system targets. The utility scans the subnet in the
range from 1 to 255. For example, if the current subnet is 10.12.77, the utility
will scan the IP addresses from 10.12.77.1 to 10.12.77.255.
•
Discover iSCSI targets for this target portal
- Discovers targets known to the
specified iSCSI SP data port. Use a specific target IP from your Network
Connections worksheet.
•
Discover iSCSI targets using this iSNS server
to send a request to the iSNS
server for all registered iSCSI storage-system targets.
5. Click
Next
. The utility scans for iSCSI target ports and displays the IP address for
each target it discovers.
6. In the
iSCSI Targets
window, select the IP address of an
Inactive
target. The
addresses match those from your Network Connections worksheet and assigned
by the initialization utility in "Initialize and enroll the storage system" on page 29.
7. Under
Login Options
, select
Also login to peer iSCSI target for High
Availability (recommended)
if the peer iSCSI target is listed. This allows the
utility to create a login connection to the peer target so that data would continue
to the peer target if the target you selected above becomes unavailable.
8. If you selected
Also login to peer iSCSI target for High Availability
(recommended)
in the previous step, leave the Server Network Adapter IP
set to
Default. This allows the iSCSI initiator to automatically fail over to an available
NIC in the event of a failure
.
If multiple NICs are on the same subnet and you leave the Server Network Adapter IP option set to
Default, only one NIC is actually used at a time. Other NICs are in standby mode. If you leave the
Server Network Adapter IP option set to Default and a NIC fails, the server will use one of the other
NICs, even if they are on the same subnet, as long as there is a network path from the storage system
to the NIC that is in standby mode.
If you are an advanced user and you want to control which network or subnet is used, you can select
a server network adapter IP address from the drop-down list. Note that failover may not occur if
you do not have the appropriate failover software.
